In my extended PreferenceActivity class I call addPreferencesFromResource(R.xml.livewallpaper_settings) so I have a xml file in which I define everything. How can I define a dialogue that asks the user to set a percentage? Maybe I could limit EditTextPreference to only accept values from 0-100?

    You may have to handle this in code, not in XML.

    1. Get the EditText of the EditTextPreference using
      getEditText().
    2. Set an InputFilter on it using setFilters()
    3. Constrain the input in the filter() method of the
      InputFilter.
